After I activated USB debugging on the now-availabe developer settings on my phone and connected it with my Mac (after connecting, choose on your phone MTP transfer in case you are asked and allow USB debugging again if asked; disconnect all other USB devices) this is what I did on my Mac:

1. I installed "Android Studio" for Mac, see here: https://developer.android.com/studio/index.html you have to run it at least once so it can finish the installation 2. opened the Terminal (you can find it easily with the searching function) and entered the following line: cd /Users/(insert here your username on your mac)/Library/Android/sdk/platform-tools 3. entered in the terminal: ./adb devices 4. entered in the terminal: ./adb shell pm uninstall --user 0 com.sonymobile.entrance (the answer of the Terminal should now be: Successfull)

Since then, What's New is marked as not installed in the App list - yippie :-)

But better be carefull, save your data with Companion first - It worked here but that doesn't ncessarily mean it'll work elsewhere...

As much as I enjoy the design of their hardware, Sony's bloatware and locked down bootloader are most likely to be focused on the Japanese market, with the cultural expectation that customers will just quietly accept whatever air they get dealt and never question or react to the manufacturer/retailer.

This may be largely to blame for Sony's shrinking user base and the recent down-sizing of their mobile division.

I was not able to get these instructions to work using talkback. I am a blind user. My new Xperia x a ultra is going back to the store. I was willing to tolerate the extreme bloatware, but I can't have these notifications going off in my classes and meetings. Goodbye sony.

Same as everyone above

Phone whining about too little space, and the problem is Sony bloatware. So update the app so Sony management gets the notivication for making it unable to delete the useless app. How many sales has the app generated for stupid themes VS unsatisfied costumers. I congradulate Sony management their incompetence, and Will warn friends about midnight /midmeeting themebuy alarms. You lost me as a costumer. Going for a clean Android next time. My Phone has mimimal a year of life left in in but is Just too annoying. Congrats to Sony for bringing it to Our e-waste Mountain,SAD.
